The Friend-Of-A-Friend Project
FOAF is a Semantic
Web project for machine-readable modelling of homepage-like content and social
networks. FOAF relies on its specification which defines terms to be used in
statements someone can make about someone else, such as name, gender and -
most interesting - online attributes. To make linking between persons and
describing social networks possible, one includes uniquely identifiable
properties of ones friends, e.g. e-mail addresses, an ICQ ID, or a URL to the
homepage or weblog of the person).
FOAF is based on
the Resource Description Framework (RDF) defined using the Web Ontology
Language (OWL). It is designed to be easily extended, to allow data to be
shared between varied computing environments. Other vocabularies' terms can
easily be integrated in a FOAF document.
In order to make
the FOAF document - typically named foaf.rdf - accessible by other
applications it has to be published on the Internet. Similarly to Rich Site
Summary (RSS), FOAF applications use Autodiscovery, embedding links to the
FOAF document inside the web page.
